cobalt has a larger atomic radius
White raven [17]3 years ago
4 0

Answer:

Radius of Cobalt > Radius of Nickel

Explanation:

In general, unionized elements in series with the lower atomic number (#protons) will tend to have a larger radius than those with higher atomic numbers. Therefore Cobalt (Atomic No = 27) would have a slightly larger atomic radius than Nickel (Atomic No = 28). A rule to remember is as atomic number increases in a series of elements the numbers of protons and electrons increase which results in an increase in the nuclear attraction for electrons thereby decreasing the atomic radius of elements.    The following periodic table of atomic radii (in picometers) will support the explanation.

What does the foundation of the continents mostly consist of?
Dafna11 [192]

Answer:

The correct answer is sedimentary rock.

Explanation:

The sedimentary rocks are the types of rocks, which are produced due to the deposition and the succeeding cementation of that substance at the shallow part of the Earth and within the water bodies. In the geological sciences, sedimentation refers to the procedure of the deposition of the solid substance from a state of solution or suspension in a fluid, that is, water or air.

What is the density of a liquid with a mass of 6 grams, and a volume<br> of 3 milliliters?
uranmaximum [27]

Answer:

2 g/mL

Explanation:

Density can be calculated using the ratio:

Density = mass (g) / volume (mL)

Since you have been given both the mass and volume of the liquid, you can calculate the density.

Mass = 6 grams (g)

Volume = 3 milliliters (mL)

Density = mass / volume

Density = 6 g / 3 mL

Density = 2 g/mL

The maximum kinetic energy of a box sliding from the top of a ramp to the bottom is A) at the top. B) at the bottom. C) at the e
Readme [11.4K]

Kinetic energy of an object can be expressed in terms of its mass m and velocity v as:

KE = 1/2 * m* v²

Thus higher the velocity, greater will be the Kinetic energy. Now, as the box moves along a ramp from top to bottom, its velocity increases and so does the KE. Hence, kinetic energy is maximum at the bottom

Ans B) at the bottom
